Troubleshooting Procedures
This LCD Monitor was pre-adjusted in the factory with standard VGA timing.
Due to output timing differences among various VGA cards, you may
initially experience an unstable or unclear display when a new display mode
or new VGA card is selected.
This LCD Monitor Supports Multiple VGA Modes. Refer to
Addendum for a listing of the factory preset modes supported
by this LCD Monitor.
PROBLEM: Display is Unclear and Unstable
To stabilize and clarify your display, follow this procedure in this order:
It’s best to adjust the display on a screen displaying of vertical lines.
In Windows, load a wallpaper bitmap that has vertical lines in it. (or
you can select the window shut down screen)
After you have the wallpaper loaded, open the OSD and select the
“Clock” function. Press the top (or bottom) Adjustment Control
button and continue pressing the button until you see vertical dark
and light lines across the screen.
When you can see distinct light and dark vertical bands, stop
pressing the Adjustment Control button. Now press the opposite
(top or bottom) Adjustment Control button. The vertical dark and
light bands will decrease in number. Keep pressing the button until
the distinct bands disappear and you have a clear display.
Next, press the Function Control button to choose the “Phase”
function. The Phase will adjust the horizontal display. Press the top
(or bottom) Adjustment Control button and you will see horizontal
dark and light lines appear. The number of lines increases as you
press the button. Now press the bottom (or top) Adjustment Control
button until the lines disappear and you have a clear display.
